Abstract: Systems, methods, devices and software for operating particle sampling devices in a user-restrictive manner include a tag and a particle sampling device. The device includes a tag reader and a processor in communication with the tag reader. The processor: receives device configuration data and reads operational and/or user data from the tag having that data encoded thereon. Based on the data read from the tag, the processor may either grant or deny access to a user for performing device operations. Alternatively, for a headless particle sampling device configured for minimal user interaction during operation, the device is removably attached to a supporting structure proximate the tag positioned in or on the supporting structure. In the headless configuration, the processor reads device configuration parameters including network communication information from the tag following device power up.

Abstract: Provided herein are methods and devices that allow for efficient management of many different sampling locations within a facility. A method for operating a biological sampler, a particle counter, and like air sampling, analysis, and/or monitoring equipment or instrumentation is described, such as by sampling an environment at a sampling position with the biological sampler and storing sample data and other useful information in memory in association with unique identifier(s) including sampling location(s) for the samples. Also provided are associated devices for carrying out the methods.

Abstract: Provided are particle analyzers and related methods for verifying calibration status of the particle analyzer, including independently of the presence or absence of particles. The method and analyzers include use of distinct and non-interfering time frequency domains: a middle frequency time domain and a low frequency time domain, and optionally a high frequency time domain. The high frequency time domain generates a laser facet drive current frequency modulation to prevent the laser facet from spatial-mode hopping. The middle frequency time domain is for particle detection. The low frequency time domain is for calibration status, including laser-pulse-light self-diagnostics, for the health or calibration status of the analyzer. By carefully selecting the frequency time domain ranges, there is non-interference, with the ability to self-diagnose the instrument that is particle-independent.

Abstract: The invention generally provides devices and methods for particle detection for minimizing human-caused contamination in manufacturing environments requiring low levels of microbes, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products, such as sterile medicinal products. Methods of the invention may incorporate wirelessly transmitting an alarm signal from a particle detector to a remote device, replicating a graphical user interface of the particle detector on an electronic display of the remote device, and passing one or more user instructions from the remote device to the particle detector via the replicate graphical interface of the remote device.

Abstract: Provided are particle analyzers and related methods for verifying calibration status of the particle analyzer. The method includes the steps of providing an optical particle analyzer and modulating a power applied to a source of EMR. The method includes the steps of, in response to the modulating step, inducing a detector signal waveform and analyzing the detector signal waveform to determine a value of at least one diagnostic parameter associated with one or more of the source of EMR, an optical assembly, a chamber, a detector, and an optical collection system of the optical particle analyzer. The method includes the step of determining a calibration status of the optical particle analyzer based on the one or more determined values of the at least one diagnostic parameter.
